DISPOSITIF DE LOCALISATION DE LA POSITION DROITE ET GAUCHE D'UN ENSEMBLE PNEUMATIQUE ET ROUE D'UN VEHICULE

A self-contained device intended to be carried by a wheel-tire assembly in order to locate whether the assembly is positioned on the right side or on the left side of a vehicle is described. The device includes two magnetic sensors with axes of maximum sensitivity, the sensors providing two periodic signals that are phase shifted relative to one another. Each signal is representative of variations in the magnitude of the magnetic field detected by the sensor during a revolution of the wheel-tire assembly. The device also includes a processing unit programmed to determine, from the phase shift between the two periodic signals, a direction in which the wheel-tire assembly is rotating and to deduce, from this direction of rotation and from a direction of travel of the vehicle, whether the wheel-tire assembly is located on the right side or on the left side. The two magnetic sensors are intended to be positioned on the wheel-tire assembly at distinct azimuthal locations. A filtering element of the device is designed to eliminate components of the two periodic signals having frequencies that are below or equal to a given frequency.
